It would be nice to make someting like fallout 3 with a sligstorm story

Slig Fortress 2. I would so play that game.

SligStorm was only planned to be the length of a single AE level and didn't have much of a story (revealed anyway) It was only about a slig that was outcast because he was albino and tries to escape from the factory...

hardly material to make a 50+ hours game.

A first person shooter oddworld style would be awesome, sorta like TF2 style, theres diffrent classes of character with diffrent moves and stuff.

How about...
Super Abe Bros.
Or Oddworld Crossing. Let's go to Necrum?

Oddworld Crossing would be uber awesome. I don't suppose anyone played Dwarf Fortress? It's a freeware low-spec game where you deal with these dwarves by making a massive cave system and putting tons of things in it. It's really customisable and very addictive :D

Nope i haven't. and how about a Age of empires sort of game only Oddworld?

*cough cough* Hand of Odd *cough cough*.

Oh yeah :D
